Biltricide is primarily intended for individuals diagnosed with schistosomiasis and liver fluke infections. It is an essential tool in the management and control of these parasitic diseases. Health authorities in endemic areas often utilize Biltricide as part of mass drug administration campaigns to combat the spread of schistosomiasis.

Biltricide’s mode of action is fascinating. It works by selectively targeting and paralyzing the nervous system of the parasitic worms. By doing so, the medication renders the parasites vulnerable, making it easier for the host’s immune system to eliminate them effectively. The paralyzed worms then detach from the host’s tissues, allowing for their expulsion through bowel movements.

Schistosomiasis, also known as bilharzia, is a neglected tropical disease that affects millions of people worldwide, primarily in developing countries with inadequate sanitation and limited access to clean water. The disease is caused by schistosome parasites, and it spreads when individuals come into contact with contaminated freshwater bodies harboring infective larvae.
